Exam 4: Fingerprint Patterns and Classification

What is the NCIC classification of an individual with the following pattern types: plain whorls on both thumbs with meet tracings, ulnar loops on the #2-5 fingers with a ridge count of 7, a radial loop on the #7 finger with a ridge count of 13, and ulnar loops on the #8-10 fingers with a ridge count of 11.

What are accidentals?

What are the two features of a whorl?

Name and describe the most common fingerprint pattern type in the population.

What are the three requirements of a loop pattern?

What are the four types of whorls?

Ridge count refers to the number of friction ridges that cross an imaginary line between the core and delta.

What features of the volar pad determine the fingerprint pattern type during human fetal development?

What technology negated the need for manual classification and filing of hard copies of fingerprint records?

Whorls are what percentage of the population of fingerprint patterns?

What is NCIC? What does it contain?

Name and describe the two features of most fingerprint patterns.

Describe the three classifications of whorl tracings.

What numerical value is assigned to each finger (#1-10) if the finger contains a whorl pattern?

What is fingerprint classification?

Why is the number one added to the numerator and denominator?

What are the various components of primary Henry classification?

Typelines are the two friction ridges, either continuous or broken, that diverge from the delta in opposite directions and surround the main pattern.

Describe NCIC classification.

Fingerprint pattern types are unique, individualizing features.
